Instead, it had the same front fascia as the Latin American Chevrolet Corsa, possibly because GM South Africa wanted the same front fascia as the sedan and pickup, as swapping with the European front fascia would have been expensive sawing and welding due to the Latin American Corsa's sharper headlights. This car was 2001 Semperit Irish Car of the Year in Ireland.
The Kadett E has been seen as a grey import in the United Kingdom, but it is quite rare compared to its badge engineered sister, the Vauxhall Astra Mk II. It was never officially sold in Britain, and by 1989, General Motors was only marketing the Vauxhall brand in the United Kingdom, although Astras assembled at Vauxhall's Ellesmere Port plant were exported to the rest of Europe badged as Opel Kadetts. There was also a van version with a raised roof, called the Opel Kadett Combo.
The Calibra was a hit, with customers lamenting the demise of the Opel Manta and the Ford Capri lining up eagerly. The Opel had competition, no doubt, with the BMW 3-Series coupe outselling it across Europe, but it was still a strong seller and its sleek looks sitting the in showroom did much to lift the image of its humbler stablemates. Ford's rival, the American-build Probe, was unable to match its success, which must have annoyed Ford as the Capri usually gave the Manta a bloody nose in the sales stakes. So confident were GM that the Calibra started to find fans outside of Europe. Holden sold its own version in Australia and New Zealand, albeit fully imported and identical to the European car, while South American markets got a Chevrolet-badged version. Rumoured US sales never happened though.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).
